Where a claimant withdraws some or all of his ET1, the respondent may apply to the tribunal for the claim, or the relevant part of it, to be dismissed. However, it will not always be appropriate for the tribunal to accede to such an application. In circumstances where, although the claimant wants to abandon his employment tribunal claim (or the relevant part of it), he also intends instead to pursue the cause(s) of action underlying that claim in fresh proceedings, and that would not amount to an abuse of process, the tribunal should not dismiss the claim, as to do so might prejudice his ability to pursue the relevant cause(s) of action in the contemplated fresh proceedings.
